A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit (outdrive or drive leg) lies outside the hull.
What is an IO motor?
A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit (outdrive or drive leg) lies outside the hull.
What's the difference between outboard and inboard motors?
The main difference between an inboard and an outboard engine is their placement in the boat. An inboard is hidden within the boat and an outboard is 100% visible. The boat on the left has an inboard or sterndrive motor and the boat on the right has an outboard motor.
What's better I O or outboard?
Outboards offer better power to weight ratio. … Outboards have a more shallow draft allowing you to fish and boat in skinnier water than you can with an I/O. Outboard motors are much more accessible and require less maintenance, no winterizing, and easier to work with the outboard outside the boat.What is the difference between inboard and Io?
Performance: An inboard outboard motor is known for more speed and boat trim ability while cruising. … Convenience: The tilt mechanisms on an IO outdrive enables a boat to go into shallower water than an inboard engine boat. Maneuverability is also easier for a boat with inboard outboard drives.
Are pontoons inboard or outboard?
Pontoon boats, in the main use outboard motors, but you will see some for sale which do actually use an inboard motor. Most of the time, though, it will be an outboard motor.
Are Inboards better than outboards?
Inboard motors generally last longer than their outboard counterparts. You can squeeze roughly 1,500 hours out of an inboard before necessary maintenance. Outboards, on the other hand, last about 750 hours on average. So, the inboard option means less maintenance (nearly half) even though they cost more initially.
Why are outboards so expensive?
The boat engine (outboard) is expensive because they need to withstand the marine environment well, so all the parts used in making one are expensive stuff. And they don’t sell numerous motors all the time, so to stay in business, they need to make a profit, so the price of an outboard (boat motor) is high.Which is faster inboard or outboard?
More Efficient Power Pound for pound, outboards deliver more power and speed than inboards. Outboard boats are several hundred pounds lighter, and less weight means your boat is faster, easier to tow, and more fuel efficient.
Can you water ski with an outboard motor?Can you ski behind an outboard boat? Outboards in the 22 to 24 foot range with a single engine (not a twin) generally work well for water skiing. Outboard boats offer very good wakes for advanced skiers, and are more forgiving than inboards for learners, allowing you to get away with less than perfect form.
Article first time published onCan you put an outboard motor on an inboard boat?
Yes, you can convert from an inboard/outboard to an outboard. Assuming someone with survey and/or hull repair experience has inspected your transom and it is sound (very important) there are aftermarket setback brackets which will bolt to your transom without modification.
Why are inboard boats so expensive?
An inboard motor will usually be more expensive due to it being located inside of the boat. This can make it more challenging when it comes to maintenance and repair. … A motor that has a higher horsepower, that can reach higher speeds is going to increase the cost.
Can you replace an inboard boat to an outboard?
Changing from inboard to outboard power can produce many benefits. It allows you to remove the motorbox from the deck, leaving more room to work. Outboard motors can deliver more precise control in maneuvering situations, and modern outboards are very efficient and environmentally clean motors.
Can you start an inboard motor out of the water?
Most outboard and inboard engines use impellers (rubber pumps) to run water to the boat’s cooling system. Without water to cool off and lubricate, the impeller will heat up super fast and possibly damage. Although you shouldn’t run your engine without water, that doesn’t mean you can’t run your engine out of the water.
What are the advantages of an outboard motor?
- Full portability.
- Far easier maintenance – just tilt.
- Simple winterizing procedure and space-saving storage.
- A Significantly lower price tag.
- Extra interior space.
- Higher potential top speed.
Why are ski boats inboard?
From creating consistent, balanced ramps to tracking true even with a hard-edging rider in tow, today’s inboards are purpose built to perfectly pull everything from wakeboarding and waterskiing to wakesurfing and wakeskating.
Are outboards louder than Inboards?
Because the entire engine is located outside the boat, there’s more room in the boat for seating or gear storage; A new outboard is cleaner, quieter and more powerful and feature-laden than the motors offered just a few years ago, all reasons they have become more popular on more types of boat.
Is 400 hours on a boat a lot?
In fact, a boat with normal hours (50-75 per year) will often time run better than a boat with low hours. … 400 hours won’t harm the resale value on a 2010 boat, but if a boat is a 2018 that is a different story.
Why do ocean boats have outboards?
The inboard designs for many also prove to be a fuel-efficient alternative. On the flip side, the outboard motor design maximizes the benefits of a directional thrust at the back of the boat, according to Outdoor Troop. This translates to increased power control, making loading and docking the boat much easier.
Are inboard or outboard motors safer?
Inboard boats are the safest style of boat for pulling a rider, but if you do plan to pull a rider with an outboard or inboard/outboard boat then all of the same safety tips for wakeboarding with an inboard boat will apply, plus some extra precautions.
What is sterndrive vs inboard?
A sterndrive is a marine propulsion system that is attached to a sterndrive, also known as an outdrive. The drive unit is both the transmission and propulsion. … An inboard is a marine propulsion system that is enclosed within the hull of the boat — it is usually connected to a propulsion screw by a driveshaft.
Do pontoons have outboard motors?
Outboards are the popular choice for pontoons, but sterndrives are a power option on some larger models.

Why are outboards so popular?
Why are outboards so popular today? Many boatbuilders point to the enhanced versatility provided by outboard power. Unlike inboards, they can be trimmed for optimal performance or to allow users to venture into shallower waters and raised right out of the water when not in use to reduce corrosion in salt water.
Why do boats have 4 outboard motors?
Compared with all three other propulsion systems that basically have an engine in the boat, using multiple outboards makes the boat faster because of a beneficial power-to-weight ratio and, in most cases, the outboards are more fuel-efficient.
How much is an outboard motor cost?
Outboard motors can range from $110 to nearly $90,000 depending on power, make, model, and other factors.
How long do outboard engines last?
A typical estimate from the industry is that an outboards motor last around 1,500 hours of operation. Assuming the average owner uses their boat 200 hours a year, this would mean that the motor would last between seven and eight years.
What is Mercury's biggest outboard motor?
Mercury’s 600 hp V-12 Verado, the world’s largest outboard, has prompted yacht builders to design new models around the engines.
What size outboard motor will pull a skier?
A 90 HP motor is the general minimum horsepower to use for a competent adult slalom skier. A boat with a dry weight of 990 lbs combined with a 90 HP engine will offer enough power for a rider up to 160 lbs to perform a successful deep-water start and slalom at a top speed of 35 mph.
How much horsepower do you need to pull a skier?
A boat should have a minimum of 70 horsepower to pull a skier. The size, weight and design of the boat will play a big part in how much horsepower you will need.
Are outboards good for wakeboarding?
Outboard Power Outboard-powered boats have been used for skiing for decades. Today, outboard-powered boats are also used for wakeboarding. Proper-selected outboard engines offer plenty of torque and are in many cases just as quiet as an inboard or I/O application.
